THE BLADE:
Known globally for its extreme strength, toughness, wear resistance, and superior properties, we precision machined our blade from M2 High Speed Steel. Designed primarily for cutting tool applications, M2 is used to make tools, bits, and blades that cut other steels and metals in various machining applications. Then, in a special furnace that’s absent of air and other gasses and capable of reaching over half the surface temperature of the sun, our blade is pushed to extremely high temperatures that change and vastly improve the mechanical properties of the steel itself. This makes it not only extremely consistent, but takes strength, hardness, toughness, and durability to an entirely different level—our level. Next, our blade is cooled down to around -300°F (close to the surface temperature of Pluto) through the use of liquid nitrogen. This changes the crystal structure of our blade on a molecular level and removes any stresses caused by heat-treatment and machining; resulting in even greater strength, hardness, and maximum wear resistance. After a few more intense processes like this, the blade is ready for the chassis.

THE FRAME:
We started from scratch. We did away with the standard of having grips layered on top of thin “cookie cutter” type liners, of which are all then held together by many small screws, spacers, pins, etc. (fail points). We built a 2-piece frame—a Chassis. Our Model 7 Chassis is 2 pieces inter-locked together—even without the use of screws (as shown) it’s already incapable of moving in nearly every direction—this eliminates the majority of the weaknesses found in most collapsible knives made today. Nothing like this has ever been done, but we wanted to achieve a level of strength never before imagined. We wanted our strength to come from design, not the amount of hardware added to the design—in fact, we wanted as few parts and hardware as possible, and this is why the chassis is only 2 parts and 2 screws. Our Model 7 Chassis is our latest design that delivers a new standard of collapsible knife strength, engineering, and precision.

THE LOCKS:
The industry problem was that blade locks on traditional out-the-front knife designs are considered by many to be “inherently weak” when compared with other collapsible knife designs such as your folding knives. We needed something stronger, something that could compete with the locks of folding knives—something that could bust through concrete, and to the best of our knowledge, locks that strong don’t exist on any knife. First we needed a lock that worked reliably, and then we needed to make it stronger than anything ever before, if that was possible. While sweeping the shop floor, the design idea was born. Within a week we had a working prototype, and as if it were meant to be, it worked reliably the very first time. After several tweaks (and broken cinder blocks) later, the official Linear Cam Locks were born. Relying heavily on the design of the chassis to create strength through synergy, our locks can withstand a variety of extreme forces on a level that we believe has never been attained in a collapsible production knife.

AWARD WINNING INNOVATIONS
As of 2024, GRIPKNIFE has been issued close to a dozen U.S. and Foreign Patents and Trademarks. While being 100% Made In USA, GRIPKNIFE is continuing to be ordered, and shipped throughout all 50 U.S. States. What gives GRIPKNIFE unique switchblade functionality, while being 100% legal?
1
ATF classified as a
Foregrip/ Handstop. Classified as a spring assisted knife by U.S. Attorneys who specialize in Knife Law.
3
One button to deploy the knife, which is not located on the knife itself.
5
2
The Magnetic-Assisted Sheath assists in functionality and reliability, as well as safe storage.
4
Spring-Assisted Blade cannot be fully retracted within the grip itself, nor can it stay in the retracted position without an external secondary part, its mounting sheath.
Blade Unlock Button is flush with the grip handle, to ensure blade is not accidentally collapsed.
